PHOTOGRAl-IIC CAMERA.

To all whom t may concern;

Be it known that I, ROBERT GoLDsTEIN, a citizen of the United States, and a resident of the city of New York, borough of Manhattan, in the county and State of New York, have invented a new and Improved Photographic Camera, of which the following is a full, clear, and exact description.

The object of the invention is to provide a new and improved photographic camera, which is very simple in construction, extremely cheap to manufacture, and arranged to permit of conveniently placing a sensitive plate in position in the camera from a magazine, and to remove the exposed plate from the camera for developing the same.

F or the purpose mentioned the camera casing is provided at the top with a slot eX- tending between a guideway adapted to receive the magazine plate holder, to allow of dropping a sensitive platel through the slot into a rack arranged within the camera casing at the rear end thereof, the said slot being controlled by a slide.

A practical embodiment of the invention is represented in the accompanying drawings forming a part oi' this' speeiiication, in which similarvcharaeters of reference indicate Corresponding parts in all the views.

Figure l is a longitudinal central section of the improved photographic camera, showing the magazine in position; Fig. 2 is a cross section of the same; Fig. 3 is a side elevation, partly in section, and showing the camera upside down for transferring the exposed sensitive plate to an acid tank for developing the plate, the said tank being shown in position on the guideway; Fig. 4t is a side elevation ot' the magazine, showing the holder partly drawn out of the shell for discharging one of the sensitive plates; Fig. 5 is a cross section or the same, on the line 5 5 of Fig. 4; Fig. G is a perspective view of the plate holder in extended position; Fig. 7 is a side elevation of a modilied form of the improvement, showing the magazine in position; Fig. 8 is a plan view et the same, the magazine being shown in dotted lines; Fig. 9 is a sectional side elevation of the magazine for the camera shown in Figs. 7 and 8; Fig. 10 is a perspective view of the plate holder of the magazine of modified form shown in Fig. 9; Fig. Il is a perspective view of the slide for controlling the admission of a sensitive plate; Fig. l2 is a reduced plan view of the casing, the

covering being removed; Fig. 13 is a perspective view of the plate holding rack; and Fig. la is a face view of the shutter.

rlie camera casing A is provided with a transverse partition B af short distance from the liront end A of the casing, and the said partition B is provided with the usual lens C controlled by a shutter D for directing the rays of light onto the sensitive plate E held in a rack F attached to the rear end A2 or" the casing, as plainly illustrated in Figs. l, 2 and 3. The rack F registers at its upper end with a slot G formed in the top A3 of the casing A, and the said slot G is opened and closed by a slide I-I mounted to slide in suitable bearings H arranged on the under side of the top A3 of the casing A.. The slide H extends to the outside of the casing at the rear end thereof, and the outer end of the slide is provided with a handle H2 adapted to be taken hold of' by the user of the camera, to move the slide lvl lengthwise in its bearings H with a view to open and close the slot G. The slide is provided with a slot H3 adapted to register with the slot G and the rack F for the passage of a sensitive plate, as hereinafter more fully described.

On the top A3 is arranged a guideway I formed of two parallel members between which extends the slot G, and the said guideway is adapted to receive the magazine J, containing sensitive plates E, for dropping one of the said plates through the slot G into the rack F for exposure in the camera, on actuating the shutter D in the usual manner.

rllhe magazine J (see Figs. a, 5 and 6) consists of a shell J, open at one end and containing the plate holder J2 having spaced chambers, each containing a sensitive plate E, the chambers being open at the bottom so that when the holder J2 is drawn out a distance corresponding to the width of a chamber, then the sensitive plate E contained in this drawn out chamber can drop out of the same and through the slot G into the rack F, as previously explained.

The holder J2 is preferably formed from a single sheet of paper, or other suitable material, the sheet being creased transversely to allow o1 felt-ling the sheet with a view t0 forming the sides J3 and It and an intermediate cut-out portion J5 for formino the chambers containing the plates E, as will be readily understood by reference to Fig. 6. ns shown in Figs. l, 2 and 3, the guideway I is arranged transversely and the holder J2 has its chambers arranged one alongside the other, so that the magazine is used transversely on the camera, as plainly indicated in Figs. 1 and 2. As shown in Figs. 7 and 8, the guideway I is arranged longitudinally on the top A3 of the camera, but between the members of the guideway extends the slot G.

A magazine K, for use between the members of the guideway I, consists of a shell K and a holder K2 having the chambers arranged one in front of the other, as plainly indicated in Fig. 9, each chamber being open at the bottom, so that when a chamber l is moved into register with the slot G, then a sensitive plate E can drop through the slot G into the rack F at the time the slide H is in open position. The holder K2 is also made from a single sheet of paper'or like material, creased to allow of folding the sheet as indicated in Fig. 10, alternate sections K8 being solid and the other sections being cut out for forming chambers K2 for the reception of the plates E. Thus, by the arrangement described, the plate holders J2 or K2 can be cheaply manufactured, and the said holders can be readily filled in a dark room and then slipped into the shell J or K, to be drawn ont of the same at the time a plate is to be transferred to the rack for exposure in the camera casing, as previously explained.

On the top A3 of the camera is arranged a sighting device consisting of the point L and an apertured post L for sighting the object to be photographed, thus insuring a `vvrproper registering of the image on the sensitive plate E held in the rack F within the casing A.

The body of the casing A, except the rear end A2, is preferably made from a single piece of sheet metal, while the end A2 and the partition B are preferably made of wood to cheapen the manufacture of the camera. The casing body has a covering A4 of paper or other suitable material, to render the camera light-tight. The guideways I are struck up from the top A3 of the metallic casing body to form the slot Gr, and the point L and the post L of the focusing or sighting device are likewise struck up from the top A3 of the metallic casing body, the apertures produced in the top A3 by the struck up point L and the post L being covered up by the covering A4, as plainly indicated in Fig. 1.

The partition B is provided at its inner face with a depression or seat B for the lens C, the seat leading to a reduced stop aperture B2 having a flaring mouth B3, as plainly indicated in Fig. 1. The shutter D Y inis formed of a single piece of sheet metal and at the outer end to form an angular handle D. The shutter is also provided with a struck up lug D2 (see Fig. 14) for engagement by a rubber band D3 also engaging a pin D2 driven into the partition B. The rubber band D3 serves as a spring to normally hold the shutter D in a closed position-that is, to cover the month B3 of the stop aperture B2. Vhen the handle D is pressed by the operator, the shutter D swings open against the tension of the rubber' band D3 and when the operator releases the handle D, the shutter swings shut, the closing movement of the shutter being limited by the handle D abutting against the side of the casing A (see Fig. 3).

The rack F is made from a single piece of sheet metal (see Fig. 13) bent to form a back F guideways F2 at the front for holding the plate E in position, and a hook F3 at the top for engagement with the upper end of the rear end A2 to hold the rack F in position without further fastening devices. The slide H is formed from a single piece of sheet metal (see Fig. 11) bent to form the handle H2 and cut out to form t-lie slot H3 previously referred to. The guideways H for the slide H are struck up from the top A3 of the casing body (see Figs. Q and 12) and the front end of the slide H is provided at its sides with depending stopl lugs H4 adapted to abut against the front ends of the guideways H to limit the outward sliding movement of the slide H, the latter in the extreme outer position having its slot H3 in register with the slot G and the upper end of the rack F. An acid tank N is used in connection with the camera for receiving an exposed plate E for the camera (see Fi 3), for developing the said plate. The tan N is also made of a single piece of sheet metal and its Open mouth is adapted to fit onto the guideway I. From the foregoing it will be seen that the camera can be cheaply manufactured.

The camera is used as follows: When the rack F is empty and it is desired to place a sensitive plate E in position in the rack from the magazine J, then the latter is placed in position on the guideway I, as in dicated in Figs. 1 and 2, and then the slide H is pulled outward into open position to allow the sensitive plate E to drop from the corresponding chamber in the holder J2 through the slot Gr and the slot H3 in the slide, down into the rack F, as indicated in Fig. 1. When this has been done, then the operator pushes the slide H inward to close the slot Gr, after which the holder is removed from the giiideway I. The object to be. photographed can now be sighted through the sighting device, and then the operator presses the self-closing shutter D to swing the latter open for making the desired exposure. When this has been done, the camera casing is turned upside down and then an acid tank N is fitted with its open mouth onto the guideway I, as plainly indicated in Fig. 3, after which the slide I-I is pulled outward to allow the exposed plate E to drop out of the rack F through the openings H3 and G into the tank N containing acid for developing the sensitive plate. As soon as the plate E is transferred, the tank N is removed, and then the camera casing is returned to normal position to allow of recharging the same with a sensitive plate from the holder J.

The camera having the guideways I and the magazine K, is used in the same manner as the one just described, the only difference being that the holder K? is shifted lengthwise of the camera for dropping a plate into the rack F instead of transversely, as is the case when using' the holder J2.

The photographic camera shown and described is very simple and durable in construction, can be very cheaply manufactured, and is not liable to get easily out of order.

The camera can be readily manipulated for making the desired exposure, for charging the camera and for developing the exposed plates.

Having thus described my. invention, I claim as new and desire to secure by Letters Patent:
